5. MAINTENANCE

Output Indicator

The purpose of the maintenance and adjustment schedule is to keep the generator in the best possible operating condition.

Inspect or service as scheduled in the table below.

There are no special operating instructions for the break in period for the engine, but the oil should be changed between the first 4 to 6 hours of operation to remove any manufacturing debris or contamination.

■ Shut off the engine before performing any maintenance. If the engine must be run, make sure the area is well ventilated. The exhaust contains poisonous carbon monoxide gas.

■ Use genuine POWERHOUSE parts or their equivalent. The use of replacement parts which are not of equivalent quality may damage the generator.

■ When repairing or replacing components of the emission control system, only use parts known to comply with EPA standards.

5.1 Emission control system

Emission source

Exhaust gas contains carbon monoxide, nitrogen oxides (NO

X

), and hydrocarbons. It is very important to control the emissions of NO

X

and hydrocarbons as they are a major contributor to air pollution. Carbon monoxide is a poisonous gas. The emission of fuel vapors is a source of pollution as well. The

POWERHOUSE generator engine utilizes a precise air-fuel ratio and emission control system to reduce the emissions of carbon monoxide, NO

X

, hydrocarbons, and evaporative fuel emissions.

Regulation

Your engine has been designed to meet current Environmental Protection Agency (EPA) and the California

Air Resources Board (CARB) clean air standards. The regulations dictate that the manufacturer provides operation and maintenance standards regarding the emission control system. Tune up specifications are provided in the Specifications section and a description of the emission control system may be found in the appendix to this manual. Adherence to the following instructions will ensure your engine meets the emission control standards.

Modification

Modification of the emission control system may lead to increased emissions. Modification is defined as the following:

 Disassembling or modifying the function or parts of the intake, fuel, or exhaust system.

 Modifying or destroying the speed governing function of the generator.

Engine faults that may affect emission

Any of the following faults must be repaired immediately. Consult with your authorized POWERHOUSE service center for diagnosis and repair:

 Hard starting or shut down after starting.

 Unstable idle speed.

 Shut down or backfire after applying an electrical load.

 Backfire.

 Black smoke and/or excessive fuel consumption.

Replacement parts and accessories

The parts making up the emission control system supplied with the POWERHOUSE engine have been specifically approved and certified by the regulatory agencies. You can trust that replacement parts supplied by POWERHOUSE have been manufactured to the same production standard as the original parts. The use of replacement parts or accessories which are not designed by POWERHOUSE may affect the engine emission performance. The manufacturers of replacement parts and accessories have the responsibility to guarantee that their replacement products will not adversely affect emission performance.

Maintenance

Maintain the generator according to the maintenance schedule in this section. Service items more frequently when used in dusty areas, or under conditions of high load, temperature, and humidity.

Air Quality Index (only for California certified models)

CARB requires that an air quality index label be attached to every certified engine showing the engine emission information for the emission duration period. The label is provided for the user to compare the emission performance of different engines. The lower the air index, the better the engine emission performance. The description of durability is helpful for the user to learn the engine emission duration period and the service life of emission control system. Refer to the warranty section of this Owner’s Manual for more information.

The air quality index label is designed to be permanently affixed to the generator and removal should not be attempted.
